The past few CES shows were all about wild prototypes and creative new products that had little chance of actually selling, but this year's event takes on a decidedly different tone. Not sure whether it's the economic downturn or the events of September 11, but there's not much flash on display (unlike the concurrent Detroit Auto Show, where hot concepts seemed to outnumber production vehicles). Instead, the focus is on technology just coming to market and variations of the tried and true. Case in point: The biggest new product category is the media center, an entertainment nerve center capable of distributing movies, music, and Internet anywhere in the home. Moxi Digital has the biggest buzz in this category, but Samsung, Pioneer, and Hewlett-Packard are showing similar boxes. In the same vein, Sampo, Sharp, and Philips have new ways of sharing photos via DVD players, TVs, and CD players.
